To all whom it may concern:

Beit known that 1, PAUL C. CLARKE, a citizen of the United States of America, re-

siding at the city and county of Denver and State of Colorado, have invented anew and useful Liquid-Measuring Tank, of which the following 1s a specification.

My invention relates to improvements in liquid measuring tanks, and the objects of the invention are: First, to provide an automatic liquid measuring tank of difierent predetermined capacities, such as pints, quarts,

half-gallons, gallons, or other quantities. Second, to provide-a li uid measuring tank that will automatically measure pints quarts, half-gallons, gallons, and other pre determined quantities of such liquids as vlnegar, milk, cream, gasolene, kerosene, and other liquids of domestic use. And third, to provide a simple, easily operated, inexpensive, and reliable liquid measuring tank, that is adapted to automatically and quickly measure out the commonly sold amounts of the various liquids of domestic consumption,

and use, that are sold in small measured quantities in grocery stores. l

I attain these objects by the mechanism illustrated in the accompanying drawings, in Which: I

Referring to the drawings, thenumeral 1,

designates a liquid holding reservoir, and 2 designates my li uid measuring tank, whic h is connected to t e bottom of the reservoir by a supply pipe 3. The liquld measurlng tank is supported underneath the reservoir;

suitable shape, to thebottomof which one.

end of the'supply i e 3 is connected, while the opposite end 0 t 's supply pipe-extends to the under side of the measuri tank, and enters a valve seat 9, which is rigidly connected to the central portion of the bottom of with a circular depression or recess,'in which is laced a dlsk 10, which I term the valve dis able manneryby which a liquid, tight joint may be maintained between the valve seat and the valve disk, but I preferably make this pivotal connection in the following manner: On the under side of the center of the valve disk I form a depending stem 1 1,=which extends through an axial aerturein the seat, around which a hub 12 is ormed, and on the stem against the under side of the hub' 12 I'- place a cup ed washer 13,which receives the end of the ub, and whichis held up against it by a Wedgekey 14, which-extends through V a slot or recess 15, formed in the under side of the Washer, and also through a slot 16in the stem. The small endof the wedge is thread-- ed, and a clamping nut is threaded to it,

which is adapted to be screwed u against the side of the washer and tightent e wedge key to press the washer u againstthe huband thus drawthe' valve isk down against its seat tight enough to prevent leakage. The cupped washer events the'wedge' key from contacting with the hub of the valve seat, andthus permits the valve to be easily turnedby the o crating handle. Below the washer' and we ge 'key, the stem 11 is tay place the 'r'eservon' upon a supthe measuringtank, and which is formed The valve disk 10 is pivotally connected centrally to thevalve seat in any suitpered, as shown, and one end ofa handle 17,

which I. term'the valve operating handle, is

secured upon this tapered portion, -by-a clampin nut 18, which'is threaded to the end oft estem.- j

A graduated quadrant bracket 19, is connected to the measuring tank support in any suitable manner, and. thisgraduated or index quadrant is provided with notches which ating handle extends. notched at equidistant points to indicate a are spaced at equal distances alpart around it, and. upon the upper side of t 1e quadrant is secured a guide plate 20, of the same curve as the quadrant, a space being left between the quadrant and plate through which the oper- The quadrant is of liquid the tank will discharge when the op-' erating handle is moved to any one of the indicating marks.

v The measuring tank is rovided with a removable cover 22, whic is preferably secured to the tank by a liquid tight joint, but

- at the same time can be removed therefrom whenever desired. The cover is provided with an air vent valve 23, which permits the oil to flow freely, when the valve is opened, and the reservoir is provided with a glass gage 23A to determine the height of the liquid therein. This glass gage is provided with the usual pipe water gage fittings, which connect at the top and bottom portions of the tank in a-well-known manner.

The" valve seat is provided with a segmental recess or chamber 24, concentrically 1 arranged with respect to the center of the seat, and adjacent to its circumference, and a threaded hole is formed at one end of this chamber, to which is secured one end of an outlet or dispensing pipe 25. The valve disk is provided with a plurality of independent liquid discharging apertures, each of which is of a diameter corresponding to the width of the chamber 24 of the valve seat, and these apertures are arranged in a con- 'centric row in the valve seat, so that each will register over the segmental chamber in the valve seat as the valve disk is turned or partially rotated by the manipulation ofthe' operating handle, as will be explained more fully hereinafter.

' In each of the valve disk apertures is screwed a tube 26, the tubes being of difierent lengths, and these several tubesdetermine the different quantities the tank is capable of measurin thus, if a pint, quart, half-gallon, and ga lon measures are required, the valve disk would require four tubes, which is the number shown, and the segmental chamber in the valve seat would H bG made long enough to drain'allfour of these tubes when the disk is moved to its ;l'irn-i t;-- or when the greatest quantity for which :the tank is arranged, is required.

Consequently, I have'illustrated four liquid discharging tubes in the valve disk, and these tubes extendingup vertically into the measuring tank, the length of each tube bearing a relative proportion to the diameter of the tank, and the tubes being arranged in the order of their measuring oapacities, the longest tube giving the smallest measuring capacity, and the shortest tube giving the largest measuring capacity. Thus the pint measuring tube is the longest, and

the quart is a little shorter than the pint, and the half-gallon tube is a little shorter than the quart tube, and the gallon is a little shorter than the half gallon, and as I preferably make these tubes all of the same diameter, they vary proportionately in length from the pint or longest to the gallon or shortest tube. The liquid measuring tank isof such an area that the amount of ii uid in the tank above the pint tubeand inc uding the contents in the tube will amount to a pint, the liquid above the quart tube and.

including what is in the quart tube as well as what is in the pint'tube will equal a quart, the liquid above the half-gallon tube and including all the liquid that fills it and also the entire contents of the'quart and pint tubes will equal a half-gallon, and the gallon tube'will receive all'of the liquid above it plus all of the liquid of the half gallon. quart, and pint tubes. The tubes of the valve disk are arranged to register with the chamber 24 of the valve seat in successive order from the pint tube around to the gallon tube; thus it a half-gallon is wanted, the operator -moves the valve disk operating handle to the half-gallon notch of the indicating quadrant, which brings the halfgallon tube above theoutlet chamber 24, together with the quart and pint tubes, as it requires all of theliquid in them, and also all in the tank above the top of the halfgallon tube, to make a half-gallon. The

valve seat 9, is provided with an inlet aper-- turc 27, which normally registers with the last measuring tube of the series, in the order in. which the tubes register with the outlet, and oil or other liquid from the reservoir passes through the supply tube 3, and the gallon tube to the measuring tank, thus keeping the said tank filled. The instant the operating handle is moved toward a desired point, the. inlet is closed, and no more liquid can enter themeasuring tank, until the'handle is restored to its normal position, when the tank immediately fills again. The upper ends of the tubes 26, may be curvedif desired, as shown at 26A Fig. 8.

My invention is simple and practical, and will actually measure such liquids as vinegar, kerosene, gasolene, cider, and other liquids, in quantities from a pint to a gallon, or a greater quantity if desired, the quantities being determined by the length. and number of the tubes.
